Ren Xuanguang, young!

Author:Lanzhou University Time:2022.09.12

Late at night, the self -study room was still on the lights, and I was reading the light -rolled and wrinkled "Inorganic Chemistry" in front of the pages in front of the page. At this point, the clock clockwise has slid through the number 2. After reading the last section, Ren Xuanliang closed the book, closed the lights, and closed the door.

Such nights are rare for Ren Xuanliang of the 2019 Grade Class 2019 Grade Culture British College. It is commonplace. Maintaining more than 15 hours a day has become his "instinct".

Power of loneliness

Ren Xuanguang has loved reading since he was a child, especially enthusiastic about reading science fiction and scientists, or swimming in the scientific story of scientists such as Zhan Tianyou and Deng Jiaxian in the scientific story of scientists such as Zhan Tianyou, Deng Jiaxian, which gradually activated his love science. , Yearning for science.

In high school, Mr. Huang Wenkui, who saw from the scientific newspapers and periodicals of the last century, was in response to the heart of "reading and filial piety to the country", responding to the national call, abandoning Shanghai's superior life and working conditions, and resolutely came to the Northwest to support the construction of Lanzhou University. The story was deeply inspired by Ren Xuanshu, and he was infected by Mr. Huang Wenkui's unsteady and concentrated scientific spirit. After the college entrance examination, he decisively applied for the chemistry major of Lanzhou University and came to this place that carried his youthful ideals.

After going to college, Ren Xuanguang maintained his good habit of reading. From the beginning, he had been scheduled to be full of life. Every day, except for class, he basically stayed in the self -study room at other times. Ri'an is home. Especially when studying at night, it is very quiet, as if it is left in this world, and it feels like loneliness has become a kind of power. "

As a basic course for chemistry, when studying the course "Inorganic Chemistry", Ren Xuanguang turned the textbook how many times, and almost "rolled the book", but he still felt that he only learned this textbook. The content of the above was not enough, so I found the textbooks of the "General Chemical Principles" textbooks of Peking University and Jilin University. In addition to the course of "Inorganic Chemistry", it is also "equally treated" for other professional courses. "I especially like to find different versions of textbooks to learn more, and I have a new understanding every time I read."

For a while, Ren Xuanguang suffered from gastroenteritis, so he often held a book while going to the toilet. This incident made him "famous" among his classmates. he. Even in order to save time to study, he did not bring a mobile phone to the study room.

After studying, running at 10 o'clock every night and playing tennis every week have become the habit of Ren Xuanluan Thunder. This is almost the only life -based transfer of life.

In the process of wide reading, Ren Xuanguang learned a lot of catalyst -related knowledge and became interested in it. At the beginning of the semester, with the encouragement of the college, he couldn't wait to apply for joining the laboratory, hoping that he could also explore the true meaning of science in the laboratory like Mr. Huang Wenkui. Fortunately, he was favored by Teacher Dong Zhengping, and he got the opportunity to optimize and improve the project to participate in the supporting materials for new catalysts.

Failure

Ren Xuanguang and several classmates in the class together form a team to jointly explore the improvement of catalysts. Under the prompt of the teacher, the team noticed that the alcohol catalytic semi -hydrogen hydrogen hydrolidal alcohol reactions were used as a widely used intermediate response in the entire chemical industry. During the catalytic process, the catalysts are required to be properly poisoned by adding aptacolin, lead and other auxiliary agents. Therefore, how to design low -cost, high -response selectivity, low -environment pollution catalytic hydrogenation process has become a realistic problem.

At the beginning of the project, how to design and prepare catalysts is more difficult for the team. Many experimental operations cannot find the answer in the book, and can only try again and again by themselves. In order to comprehensively and accurate experimental data, "we often stay in the laboratory all day long and record the experimental phenomenon." But even so, the experimental results are still mostly failed. "Sometimes it may be done for a month. get".

The roasting process is the step of the team's most failed. During the roasting, precious metal nanoparticles are very easy to reunite. In order to find a supporting material that can overcome this problem, the team has synthesized and improved 17 different materials for the loads for precious metal nanoparticles. In the process of synthesis, the team "has failed a hundred times", but everyone never thought of giving up. On the contrary, Ren Xuanguang believed that "every failure of each fail It's a step closer to the correct answer. "

After a year and a half, the team finally found that the method of wrapping precious metal active sites inside the interior material can solve the problem of reunion. Ren Xuanguang believes that in the process of this process, in addition to the success of the project, there is also a basic grasp of the use of laboratory equipment and equipment, and more importantly, the development of the literature through the problem of discovery, the problem, and the problem solving the problem, etc. Scientific thinking of the process.

power of the team

After completing the laboratory preparation process, Ren Xuanguang did not stop at the innovative results achieved during the experimental research stage. He believes: "If it is only staying in the laboratory, then this study can be said to be meaningless." To make a item The transformation of scientific achievements into real productivity is an indispensable link. With the help of Teacher Dong Zhengping, the team and a chemical enterprise reached cooperation. The results of the early experimental results entered the industrial production stage from the laboratory. reduce. To solve this problem, the team members launched a new round of learning and experiments, and continued to explore the design of a series of hollow media silicon capsule carriers to load precious metal catalysts in order to optimize this response step.

Kung Fu is worthy of care. Finally, the team designed a new type of media silicon nano -capsule that can solve this problem. The new type of medium silicon nano -capsule loading precious metal catalyst not only has the advantages of strong acid resistance, loss of activity group loss, and high stability, but also greatly reduce the pollution of water bodies in traditional methods. Compared with the previous products, this new type of catalyst can also catalyze the reaction in an environment with strong acid and alkali, and its use range has been effectively expanded. In terms of catalytic efficiency and performance of the product, the efficiency of the new catalyst can remain more than 90%after experiencing 14 catalytic, and the catalytic efficiency of traditional catalysts will drop to 70%after reusing 6 or 7 times.

With this achievement, with the strong support of Teacher Dong Zhengping and the Duying College and School Youth League Committee, the team participated in the seventh China International Internet+College Student Innovation and Entrepreneurship Competition under the title The creative group of the Gao Education Lord Circuit won the National Gold Award, and achieved a zero breakthrough in Lanzhou University on the track.

In order to win in the Internet+contest, in addition to the quality of the product itself, the writing of the application for the application and defense is also the top priority of the event. From the school competition to the provincial competition to the national competition, the team's business plan is getting thicker and thicker. "The business plan during the school competition is only about 20,000 words; in the provincial competition, we further expanded the application scope of the product; when the national competition, the entire production line was clearly reflected." From the details of PPT, to the wording of the defense, and even the speed of speech, the team is repeatedly discussed with the teacher, and it is polished to perfect in half a year. Recalling the hard experience, Ren Xuanguang said with a smile: "At that time, the teacher came to" torture "every night."

Dream

"From macro -macro -changes to a micro -perspective of nano -level, the physical chemical properties of matter will change greatly." In the process of engaging in catalyst -related research, Ren Xuanguang observed that some basic particles reacted at the nano -level scale. Changes in nature have made him have a strong interest in nanochemistry.

A lesson of "Nanochemical" set up in my junior year provided Ren Xuanguang with the opportunity to learn in -depth knowledge of nanochemical related knowledge. He was immersed in it hungry. Fortunately, Mr. Zhang Haoli, who taught the course, did not focus on "instilling" knowledge in the lecture. It is focusing on cultivating students' scientific research thinking. "He will let the students put forward a topic of interest, build a scientific research project in a way of thinking storm, and follow the background of the application template writing problem, implementation plan and significance of the application template writing of the National Scientific Research Fund."

During this training process, Ren Xuanliang gave up the idea of ​​designing a photon multipliers to improve the power generation efficiency of the silicon -based solar cell. At present, the theoretical community believes that single -linked solar cells have a upper limit that cannot be broken in theory, and photon multipliers can turn a high -energy photon that cannot be absorbed by a single silicon -based solar cell to two. The absorption band is 1.1 electronic volt low -energy photon, which achieves the effect of more photons absorbing, thereby improving the upper limit of the power generation of this solar cell. Due to energy loss and other issues, the current research of the scientific community on photon multiples is still at the theoretical vision stage.

With the guidance and help of Teacher Zhang Haoli, Ren Xuanguang designed a new type of photon multiplocker based on the principle of SF and TADF, which is expected to overcome the problem of low light lighting efficiency and separation, thereby achieving 200%ideal photon multiplier efficiency. He introduced excitedly: "If this research is successful, then this photon multiplier will increase the efficiency of single silicon -based solar cells by 6%, which also means Breakthrough! "At present, Ren Xuanguang has cooperated with the laboratory's brother Zhang Boyang to complete the preliminary synthesis of the materials." What to do next is to verify this idea. "

Speaking of the study experience at Cuiying College in recent years, Ren Xuanguang felt that he had gained a lot: "Cuiying College has strongly encouraged and supported us to participate in academic competitions such as the Internet+, so that we have consolidated professional knowledge in innovation and entrepreneurship, cultivated us The awareness of innovation has enhanced our ability to ask, analyze and solve problems. "The three -year average academic performance point ranks first, applied for two items as a co -inventor, and obtained the seventh China as the project leader of the project. The international "Internet+" college student innovation and entrepreneurial contest gold award, won the national scholarship for two consecutive years, and gratitude to the Chinese modern scientists scholarship, and recently won the 13th "China Youth Science and Technology Innovation Award", which became the award for our school Third undergraduate student. With such achievements, Ren Xuanguang will go to the School of Chemistry and Molecular Engineering of Peking University after graduating next year to further engage in his deep love of chemistry learning and research. As I wrote: "For a long time, I have been thinking about a question, what kind of way to go in the future, what kind of person to become a person, after understanding the life of his predecessors, after experiencing some scientific and technological innovation activities, I miss me With the answer, our young people have done their lifetime power, all their life, seeking knowledge, reporting to the country, and benefiting the people, and bowing for the party and the country for the people! "Recently, the Communist Youth League Central Committee, the National Youth Federation, the National Federation of Studies, the National Young National Little The results of the 13th "China Youth Science and Technology Innovation Award" hosted by the Working Committee were announced. Ren Xuanshuang, a 2019 undergraduate student in the 2019 Grade Institute of Our School, won the honor. Ninth student and third undergraduate student.

The "China Youth Science and Technology Innovation Award" was established in 2004. On the occasion of the 100th anniversary of Comrade Deng Xiaoping's birthday, with the approval of the Party Central Committee, according to Comrade Xiaoping's last wishes, Comrade Xiaoping donated all the manuscripts of Comrade Xiaoping's life. The National Federation of Studies and the National Young Working Committee jointly established the "China Youth Science and Technology Innovation Reward Fund" and carried out the "China Youth Science and Technology Innovation Award" selection. So far, more than a thousand students have won the lofty honor of the "China Youth Science and Technology Innovation Award", and a large number of outstanding young scientific and technological talents have produced an important role in scientific research institutions and innovation fields.

Our school has always attached great importance to the cultivation of scientific and technological innovation talents and the creation of double innovation atmosphere, continuously rationalize the innovation and entrepreneurial system and mechanism, strengthen innovation and entrepreneurial service capabilities, actively cultivate newcomers with innovative spirit, guide the young students of our school to build new merits in the western land to build new achievements in the western land. era.
